About this Gig

Want to build a complete, professional audio system on a single integrated PCB? I will design and integrate your amplifier, preamplifier, and Bluetooth audio circuit into one clean, optimized PCB system.

I will handle the full design from schematic capture to PCB layout delivering a system that is electrically clean, thermally managed, and ready for prototyping or mass production.

What the system includes:

  • Power amplifier stage (Class AB, Class D, or TDA-based)
  • Preamplifier with volume and tone control
  • Bluetooth audio receiver module integration (CSR, QCC, or similar)
  • Shared or separate power supply design
  • Audio input selection circuit
  • Protection and mute circuits

Full deliverables:

  • Complete system schematic
  • Multi-layer PCB layout with proper audio routing
  • Gerber files ready for fabrication
  • Full BOM with sourcing links
  • 3D PCB preview and assembly notes
  • LTspice simulation for critical stages

This is the complete package for anyone building a serious audio product. Message me with your specs and let's design something exceptional!
